●The sealant has a limited lifespan. The expiry date is marked on the bottle.
The bottle of sealant should be replaced with a new bottle before the expiry
date. Contact any authorized Toyota dealer or repairer, or another duly qual-
ified and equipped professional for replacement.
● If the sealant gets on your clothes, it may stain.
● If the sealant adheres to a wheel or the surface of the vehicle body, the stain
may not be removable if it is not cleaned at once. Immediately wipe away
the sealant with a wet cloth.
● During operation of the repair kit, a loud operation noise is produced. This
does not indicate a malfunction.
● Do not use to check or to adjust the tire pressure.
WARNING
■ Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.
■ Caution while driving
● Store the repair kit in the luggage room.
Injuries may result in the event of an accident or sudden braking.
●The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
●Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident causing death or serious injury.
■ Precautions for use of the sealant
● Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
● If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.

WARNING
■ When fixing the flat tire
● Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or
other body parts may result in burns.
● To avoid risk of burst or severe leakage, do not drop or damage the bottle.
Visually inspect the bottle before use. Do not use a bottle with shock,
crack, scratch, leakage or any other damage. In such case, immediately
replace.
●Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur
as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that
the hose will move abruptly due to air pressure.
● After inflation of the tire has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
●The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 minutes.
● Parts of the repair kit become hot during operation. Be careful when han-
dling the repair kit during and after operation. Do not touch the metal part
8
around the connecting area between the bottle and compressor. It will be
extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the
one indicated. If the sticker is attached to an area where an SRS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS
airbag from operating properly.

WARNING
■ Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
●Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
● If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 130 kPa (1.3 kgf/cm2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■ When performing an emergency repair
● A tire should only be repaired with the emergency tire puncture repair kit if
the damage is caused by a sharp object such as nail or screw passing
through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergency repair with the repair kit.
●The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction may
occur.
